Ambulatory Blood Pressure Monitoring

This is a test whereby your your blood pressure is recorded at regular intervals over a 24-hour period.

On a belt around your waist, you wear a portable recorder which is attached, through tubes under your clothes, to a cuff which is wrapped around your arm. You carry on with your normal daily activities and, every hour or so, the cuff automatically inflates and measures your blood pressure. The recorder keeps a record of each blood pressure measurement and the time that it was taken. The next day, when you go back to hospital, the device is taken off. It then prints out a record of all the blood pressure measurements made during the previous 24 hours.

This test gives an overview of all the blood pressure readings throughout the 24 hours. It is particularly useful if your doctor thinks that your blood pressure is unusually high when you have it measured in the surgery or at hospital appointments.
